I think your food situation is a little more complicated than mine. My other youngster was a feral rescue and I swear he has to check every dish in the house to see if there is something better than what he got. He plays musical dishes at mealtimes much to the chagrin of his siblings. My only solace is that when I leave out extra food, as long as he hasn't gobbled it all up, Menace will shove him right out of the dish if she wants food and lately he seems to be letting her do it without any further attempt to get at it.
My big news is that I actually caught Menace licking up the last bits of wet food on Monday afternoon when I refused to give her more of her kibble. I darn near fainted on my kitchen floor. So of course, I offered her more of the wet food even though it was about 13% carbs....anything to get her to eat wet food but alas it was not to be. I've continued to offer it to her for every meal and snack since and she's back to burying it. I guess the good news is that if she were running really low, she might actually dig into some wet food. The problem is that I leave wet food down much of the time for my geriatric fellow who grazes so I am now wondering if Menace might be pilfering more than I am aware of. I'd sell my soul to get her to eat canned food!
